Chapter 7: The Evaluation Of Ontologies, Leo Obrst, Benjamin Ashpole, Werner Ceusters, Inderjeet Mani, Steven Ray, Barry Smith

Steven R Ray

Recent years have seen rapid progress in the development of ontologies as semantic models intended to capture and represent aspects of the real world. There is, however, great variation in the quality of ontologies. If ontologies are to become progressively better in the future, more rigorously developed, and more appropriately compared, then a systematic discipline of ontology evaluation must be created to ensure quality of content and methodology. Systematic methods for ontology evaluation will take into account representation of individual ontologies, performance and accuracy on tasks for which the ontology is designed and used, degree of alignment with other ontologies …

Inventions On Ldap- A Study Based On Us Patents, Umakant Mishra

Umakant Mishra

Lightweight Directory Access Protocol (LDAP) is an IETF open standard to provide directory services in the network. LDAP is based on X.500 directory architecture, intended to provide directory services in Internet compatible environments. LDAP is used to provide directory services to applications ranging from e-mail systems to distributed system management tools. LDAP is becoming more and more popular with its wider usage in the Internet.

This report on LDAP is based on a study of 60 selected patents on LDAP from US patent database. The objective of this article is to present the distribution of patents according to different features …

Prospects And Possibilities For Ontology Evaluation: The View From Ncor, Leo Obrst, Todd Hughes, Steven Ray

Steven R Ray

In this position paper, we briefly describe the perspective of the US National Center for Ontological Research (NCOR, http://ncor.us) on ontology evaluation. NCOR’s inauguration was recently held (October 2005), and at that time goals were identified and committees formed to pursue those goals, including the Ontology Evaluation Committee. This committee is charged with developing a plan for the evaluation of ontologies that is designed to transform ontological engineering into a true scientific and engineering discipline. This paper discusses some issues on ontology evaluation, including the relevant questions to ask, and suggests some approaches.

The 2006 Upper Ontology Summit Communique, Leo Obrst, Patrick Cassidy, Steven Ray, Barry Smith, Dagobert Soergel, Matthew West, Peter Yim

Steven R Ray

On March 14-15 in Gaithersburg, MD, at the US National Institute of Standards and Technology (NIST), the Upper Ontology Summit (UOS) took place. The Upper Ontology Summit was a convening of custodians of several prominent upper ontologies, key ontology technology participants, and interested other parties, with the purpose of finding a means to relate the different ontologies to each other. The result is reflected in a joint communiqué, directed to the larger ontology community and the general public, and expressing a joint intent to build bridges among the existing upper ontologies in ways designed to increase and rationalize their utilization …

Manufacturing Interoperability, Steven Ray, Al Jones

Steven R Ray

As manufacturing and commerce become ever more global, companies are dependent increasingly upon the efficient and effective sharing of information with their partners, wherever they may be. Leading manufacturers perform this sharing with computers, which must therefore have the required software to encode and decode the associated electronic transmissions. Because no single company can dictate that all its partners use the same software, standards for how the information is represented become critical for error-free transmission and translation. The terms interoperability and integration are frequently used to refer to this error-free transmission and translation. This paper summarizes two projects underway at …
